Solving Azure Web Application’s first load perfomance issues
Reading Time: 3 minutes. This post was most recently updated on October 9th, 2018.Is your Azure Web Application suffering from absolutely horrible load times every time someone accesses it for the first time every 15 minutes or so? Mine was. It was pitiful. I was developing a web-based service using EF6 and ASP.NET MVC 5, where all the assets were hosted in the Azure. Even though the app was reasonably lightweight and usually responded very fast, the first time someone accessed it in a while it took 20-60 seconds to load AND sometimes even timed out (especially with mobile clients). Load testing revealed only […]

Reading Time: 10 minutes. This post was most recently updated on October 9th, 2018.In this post, I’ll try to archive everything you need to download and install to get commandlets like Connect-MsolService working.

Mostly this comes to play, when you’re switching machines, try to run the SharePoint Online Management shell but it doesn’t even exist on the machine, or it does exist but you get random errors like this: […]

Disabling Delve/MySite redirection from SharePoint Site Collections
Reading Time: 2 minutes. This post was most recently updated on October 9th, 2018.In this post I instruct a simple way to stop SharePoint (either on-premises installation or SharePoint Online) from redirecting to MySites or Delve. The normal behavior is, that this happens when users click any name of a user anywhere in SharePoint. This is often not desired, and sometimes just confusing or impractical. Problem If your customers are like mine, a lot of them hate Delve or MySite or both. Or maybe they just are’nt willing to yet adopt Delve. Or maybe they just want to simplify the team site experience for […]

The problem and symptoms Okay, so you’re developing your MVC+EF cool web app with a database in Azure, and you’re using code-first migrations. Cool! What’s nice with code-first-migrations is the fact they are run automatically even in the cloud the next time your app is running (as long as you publish your app with that little box ticked – something like […]

This post was most recently updated on October 28th, 2018.This post describes one of the more no-brainerish ways of fixing a ‘System.OutOfMemoryException’ exceptions being thrown in your ASP.Net MVC application using C# and Entity Framework.

Using PowerShell to set ULS logging level to “extra verbose” to catch all the events in the logs
Reading Time: 3 minutes. This post was most recently updated on October 9th, 2018.This blog post describes how set the SharePoint’s ULS level to “Extra Verbose” (VerboseEx) using PowerShell. This is not possible using the browser UI, so some POSH magic is required! Luckily, it’s quite straightforward, but to avoid filling your hard drive(s) with huge log files, you should reset the level when you’re done debugging! Description of the solution By default, ULS logging is somewhat non-detailed. This means that a lot of data that could be used to debug issues is omitted. The UI cannot be used to set this level of […]
Using PowerShell to modify anonymous access permissions on SharePoint On-Premises
Reading Time: 2 minutes. This post was most recently updated on October 9th, 2018.This post is about managing Anonymous Access on a SharePoint site (SPWeb) using PowerShell commandlets. It’s often a lot more feasible and even easier than using the browser interface! In some cases, it’s borderline impossible to avoid it anyway – since accessing the GUI switch might not be possible. Description Assume you have a site collection that’s you have published to the whole world. You’ll have anonymous access enabled at both web application and site collection -levels, and configured permissions at the root web -level. Now, let’s assume you want to […]
Powershell Error: Cannot uninstall the LanguagePack 0 because it is not deployed.
Reading Time: 2 minutes. This post was most recently updated on October 9th, 2018.Have you ever run into this, very non-descriptive and weird SharePoint error message “Cannot uninstall the LanguagePack 0 because it is not deployed”?

Symptoms Assume you’re trying to install, update or uninstall a SharePoint solution (.wsp package) using PowerShell-commands Install-SPSolution, Update-SPSolution or Uninstall-SPSolution (respectively). Operation fails with the following (or similar) error: Error: Cannot uninstall the LanguagePack 0 because it is not deployed I have actually […]
“Server Error in ‘/’ Application” or “Parser Error” – it’s actually a malformed web.config killing your ASP.NET-application or SharePoint
Reading Time: 2 minutes. This post was most recently updated on October 9th, 2018.This post describes how to resolve a kind of cryptic and oddly misdescriptive error message about Parser Error on your ASP.NET application or (an On-Premises) SharePoint site. I ran into this after deploying wsp-packages to a SharePoint farm, but you can apparently get this on ASP.NET MVC sites, too. The error doesn’t actually tell you what’s wrong, so figuring it out took a while. Hopefully it’ll help you, though! Symptoms: Parser Error from a random-looking location Once you navigate to your web- or SharePoint site, you only get an error like this: Server […]

Solution The Design view requires connection to the SharePoint site where you’ll be deploying the […]

UPDATE 11.4.2016: I actually got this nasty exception on another occasion (Azure webjob publish), so I updated the text accordingly. Symptoms Visual Studio throws the following error when packaging a SharePoint solution to a .wsp […]
Identifying IE11 compatibility mode in SharePoint
Reading Time: 4 minutes. This post was most recently updated on October 9th, 2018.In this post, I describe how you can figure out if IE11 has jumped in the compatibility mode. This is quite important because in compatibility mode IE does its best to screw up your CSS. Compatibility view now and before Microsoft has been pretty keen on introducing new ways to handle browser compatibility and make IE behave in even stranger ways that it usually does by switching it to compatibility mode. There are a few reasons this could happen. In SharePoint’s case, perhaps the most usual one is that IE identifies the […]

There are quite a few reasons that can cause this error, but after the obvious ones (some files failing to be included in the package, botched wsp deployment, errorenous urls in event receiver) one thing to check might be the alternate access mappings.

Attaching the Visual Studio debugger to the right IIS worker process
Reading Time: 2 minutes. This post was most recently updated on October 9th, 2018.Every now and then comes the time when you’d actually need to debug something, and then you’ll likely be using your Visual Studio to attach the debugger to one or more processes. Using CKSDev to attach to all IIS worker processes (w3wp.exe), or if you don’t use CKSDev, just pressing ctrl+p and selecting the processes from the list, is often a good enough solution. However, sometimes that makes your dev box sluggish, or maybe catches exceptions from code you’re not wishing to debug at the time, and it’d be handier to […]
